技术领域

背景技术
现有的印刷生产工艺主要有平压平丝网印刷方式和轮转丝网印刷方式。传统平压平丝网印刷方式印刷速度低、油墨固化速度慢、印刷质量难于控制、印刷材料消耗大，无法满足规模化、批量化的生产需求。轮转丝网印刷采用圆筒形丝网印版，圆筒内装有固定的刮墨板，圆筒印版与承印物作等线速度同步移动的印刷方法。丝网印刷属于直接印刷方式，适用于小批量生产，印刷外观要求较高、纸板厚度不限、不损害强度的包装产品。轮转丝网印刷最主要区别于其他的印刷方式是高速性、和其他印刷方式的整合性、一次性模切成型，更高效，快捷。

S52：静止过程中，外设的UV烘干灯箱31对印刷完成后的承印材料进行烘干；
S53：设定时长结束后，收纸链叼牙排32运转，将烘干后的承印材料输送至收纸台33。
于其他更具体的实施例中，卷筒纸轮转丝网印刷使用镍金属圆丝网印版、内置刮墨刀和自动供墨系统，刮墨刀将印刷油墨从圆丝网版上转移到由压印滚筒支承的承印物表面。整个印刷过程从进纸、供墨、印色套准，UV干燥等均由电脑全自动控制，可以通过外设智能终端联机烫印全息防伪标识、凹凸牙印、模切压痕，易于实现高速自动印刷纸盒。
综上所述，本申请的一种丝网印刷系统及其印刷方法，基于将平面承印材料在印刷过程中卷制成筒状承印材料的技术特征，满足特殊印刷效果的要求，印刷材料提供连贯，材料间连接紧密性、平整度佳；由于采用高速轮转丝网印刷生 产线的技术特征，印刷速度快、生产率高、印品质量稳定、消耗承印材料数量少；基于外设控制电路的技术特征，能够联机烫印、实现高速自动印刷，省去高昂人力物力及时间成本，提高生产效益；本申请提供的丝网印刷系统及其印刷方法，功能完备，结构简单，造价低廉，使用寿命长，具有广阔的应用前景。
上述仅以实施例来进一步说明本申请的技术内容，以便于理解，但不代表本申请的实施方式仅限于此，任何依照本申请所做的技术延伸或再创造，均受本申请的保护。本申请的保护范围以权利要求书为准。
